Non Abelian BF theories with sources and 2-D gravity
J. P. Lupi, A. Restuccia, J. Stephany
Abstract
We study the interaction of non-Abelian topological BF theories defined on two dimensional manifolds with point sources carrying non-Abelian charges. We identify the most general solution for the field equations on simply and multiply connected two-manifolds. Taking the particular choice of the so-called extended Poincaré group as the gauge group we discuss how recent discussions of two dimensional gravity models do fit in this formalism.
